Learn Morse Code (CW)

Here are some good videos I’ve been finding to learn morse code.

Experience the nostalgia of a good old training film. Beats me what the purpose of the lady,gun,and piano is.

K4CD has turned me onto CW Academy. They use the KOCH method of learning CW. Here is a link to the resources page: http://www.cwops.org/cwa-student-res.html

Learn CW Online is another resource:
http://lcwo.net/courseintro

Why CW? Because you can send long distances with lower power using less bandwidth than a phone transmission.

I am learning it because a lot of the el-cheapo QRP kits are CW transceivers.

Enjoy,

You’ll need a directional antenna like this one linked above. Easy to build. Don’t worry about tuning it. You will be primarily using it for receive.

Baluns and Chokes

This was actually a very good explanation of Baluns and Chokes.

You’ve heard a lot of people recommend putting a few loops of coax near the feed point of your antenna to keep the RF energy out. How does this work and why is it needed. Watch this episode for more information on common mode currents, baluns, and RF chokes.
